Abstract

Distal stent size selected by estimated normal aorta size could promote full remodeling at the dissected aorta after TEVAR, with low risk of distal SINE.Clinical ImpactDistal stent size selected by estimated normal aorta size could promote aortic remodeling and false lumen complete reduction (full remodeling) at stented section after endovascular therapy in type B dissection patient.
